Answer:
commutative
Step-by-step explanation:
you are typing the same numbers but in different order
Answer:
1. 650, 700 2. 840, 800 3. 370, 400 4. 80, 100 5. 620, 600 6. 250, 200 7. 970, 1,000 8. 330, 300 9. 450, 400 10. 210, 200 11. 100, 100 12. 710, 700
Step-by-step explanation:
Answer:
f(10) = 3(10) - 2 = 28
Step-by-step explanation:
The numbers are 3+2+3=8 , the first number minus the second and the third is 4 then you get 3-2+3=4
So your overall anwser is 3+2+3=8
Answer:
Gah! Inverses!
Step-by-step explanation:
This is a pretty simple concept, just switch the x and f(x) values!
If you don't understand, look at how I solve it!
![f(x)=\frac{1}{3} -\frac{1}{21} x](https://tex.z-dn.net/?f=f%28x%29%3D%5Cfrac%7B1%7D%7B3%7D%20-%5Cfrac%7B1%7D%7B21%7D%20x)
Switching the positions of the x and f(x) values...
![x=\frac{1}{3} -\frac{1}{21} f(x)^{-1}\\](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B1%7D%7B3%7D%20-%5Cfrac%7B1%7D%7B21%7D%20f%28x%29%5E%7B-1%7D%5C%5C)
Note: That f(x)^-1 is the proper notation for inverse functions.
![x-\frac{1}{3} =-\frac{1}{21} f(x)^{-1} \\f(x)^{-1}=-21x+7](https://tex.z-dn.net/?f=x-%5Cfrac%7B1%7D%7B3%7D%20%3D-%5Cfrac%7B1%7D%7B21%7D%20f%28x%29%5E%7B-1%7D%20%5C%5Cf%28x%29%5E%7B-1%7D%3D-21x%2B7)
There you go!
Hope this helps, and don't procrastinate!
